Voiceover actress for Apple's Siri attending Fort Myers conference

You could call it the most famous voice in the country or possibly the world: Siri, the voice of Apple's iOS devices.

It's the digital personal assistant that helps us navigate around town, find our favorite restaurants, and even think about the meaning of life. But many don't know the face behind the famed voice.

For the past four years, Susan Bennett's voice has been larger than life.

"It was a total surprise to all of us," Bennett said.

And it truly came out of nowhere.

"We had no idea where they were going to end up. We thought we were recording for phone systems."

In 2005, Bennett spent hour after hour in a sound booth reciting sentence after sentence, phrase after phrase, all eventually programmed together to create the original voice of Siri.

When Siri launched, she received an e-mail from a friend and was shocked.

"On October 4, 2011, when Siri first appeared on the iPhone, she wrote and said 'hey, we're playing with this new iPhone. Isn't this you?'"

Apple bought the recordings to use while creating Siri, and Bennett never saw a dime. But she said it has opened up doors for her she would have never had, and she has no regrets. There is a lot more to becoming Siri than you may think.

"Every phrase had to be said in the same way, the same pace, the same pitch, the same intonation, and it gets very boring," Bennett said.

So if you think you can just step into the booth and become the next voice that guides iOS users across the globe, think again.

"It's like anything else; it requires skill, and practice, and work, and time."
